How to play with Polyphonic Aftertouch on Channel Pressure “only” synths. You need a synth with multi patch support like the Oberheim Xpander, Studio Electronics Code 8 and Alesis Andromeda.
Arturia has announced availability of iSEM, its second subtractive synthesizer recreation for Apple’s iPad. Here’s the story in their own words…
Like Arturia’s Oberheim SEM V desktop (or laptop) software solution before it, iSEM uses proprietary TAE (True Analog Emulation) technology to faithfully reproduce the analogue warmth and ingenious interface of the vintage Oberheim Synthesizer Expander Module (SEM) to which it also owes its inspiration and name, but brings it all kicking and screaming to this day and age in the most musical and ingeniously interactive ways possible by making the most of the latest developments available to its iPad host. Helpfully, Arturia has seen fit to take advantage of iOS 7’s inbuilt Inter-App Audio, allowing iSEM users to send MIDI commands and stream audio between apps on the same device. And that’s just for starters!
But first, a little history: hatched by legendary synth designer Tom Oberheim back in 1974, the dual-oscillator SEM was originally conceived as a way of beefing up weaker-sounding compatible analogue monosynths of the time before becoming a sought-after sound in its own right — so much so that its American creator came up with a series of successive SEM-based instruments, first pairing up two SEMs with a 37-note keyboard and a simple analogue step sequencer to form the Two Voice, Oberheim’s first self-contained compact, duophonic synthesizer in 1975, thereby beating rivals to the polyphonic punch. Programmability came courtesy of Oberheim’s breakthrough Polyphonic Synthesizer Programmer which — when hardwired into the fair-sized Four Voice (featuring four SEMs and a 49-note keyboard) in 1976 and enormous Eight Voice (eight SEMs set across two tiers) in 1977 — enabled the control voltages of many parameters for up to eight SEMs to be memorised for the first time. Though these instruments were undeniably groundbreaking, quickly finding favour with the likes of popular prog-rockers Rush and electronic music trailblazers Tangerine Dream, polyphony was, after all, achieved with multiple SEMs so each voice/module had to be programmed independently, which was quite a daunting task — even by somewhat shaky Seventies standards!
Fast forward, then, to 2013 and the truly 21st Century musical landscape has changed considerably, as has music technology itself. Today, of course, we take polyphony and programmability for granted, though not necessarily that still-sought-after Oberheim sound. Ingeniously, iSEM quite literally taps into all of this and then some, putting more musicality at anyone’s fingertips than its analogue namesake designer dared dream possible back in Oberheim’s Seventies salad days!
On the surface, anyone in any way familiar with the original Oberheim Synthesizer Expander Module® will immediately feel right at home when launching iSEM since the majority of its MAIN screen graphically mirrors the VCO 1, VCO 2, VCF, ENV 1, ENV 2, and LFO 1 layout and all associated controls to a tee — right down to the old Oberheim logo within the VCF section! Speaking of recognition, recreating that still- sought-after Oberheim sound is a challenge that iSEM readily rises to meet from deeper within thanks to that TAE® technology. This allows accurate modelling of analogue circuitry behaviour — in this case, an original Oberheim Synthesizer Expander Module®. Meaty, Seventies- sounding sounds stream forth from iSEM with over 600 highly-usable presets always accessible from its eye-catching browser — a quantum leap forward from Oberheim’s Polyphonic Synthesizer Programmer of way back when, surely?
Of course, communicating with the outside world in the pre-MIDI age was always a testing time back in the Oberheim SEM-launching Seventies. Not so today with iSEM… simply tap CONNECT and the iPad world is your musical oyster, thanks to Core MIDI, WISTTM, and Audiobus support — not forgetting the aforementioned Inter-App Audio.
But that’s not all iSEM has to offer. Far from it, in fact! Pressing the VOICE PROG button brings into play a voice programmer that makes simulating a huge polyphonic sound similar to Oberheim’s original Eight Voice hardware heavyweight a breeze — albeit without having to wrestle with eight monosynth modules hardwired together to create complex tones. Tellingly, MOD MATRIX makes creating complex modulation routings equally easy while the FX page brings built-in chorus, delay, and overdrive effects into the musical mix. Meanwhile, multiple performance parameters are accessible from the PERF page boasting ARPEGGIATOR controls, assignable sliders, and effects mix controls.
Amazingly, all of this is available in iSEM as an ear-opening iPad app for a tiny fraction of what its notable namesake analogue ancestor cost almost 40 years ago. The times they are a-changin’ here for sure! And admit it. Will you miss having to haul heavyweight hardware around? That’s progress. Portability pluses apart, iSEM is a supreme software recreation of a supreme subtractive synthesizer, pure and simple. So surely Apple’s App Store should be your next port of call? Get iSEM today and get back to the future of that still-sought-after Oberheim sound with Arturia!
Appropriate iPad owners can purchase and directly download iSEM from Apple’s App Store for $9.99 USD/€8.99 EURO/£6.99 GBP
This is an in-your-face review of the Oberheim Drumulator Audio Synthesizer (Waldorf Micro Q + Novation X-Station 25).
This was the first Gluten Free iPad Synthesizer App from 1977.
Background video description:
A fellow VSE’r was wanting to know how to sync his JP-8’s arpeggiator to his DMX. I don’t know of any way to do that directly without another piece of gear in between to convert clock pulses.
The Garfield Electronics Modulator can program trigger pulse rhythms up to 2 measures synched to 24ppq DIN, 24, 48 or 96ppq phone jack.
Checking out the Oberheim SEM Pro, background video description below:
“Just had it for a day or two, so I’m still a bit hunt-and-peck when it comes to the controls. Sounds delightful though. No effects, straight into a mixer and out to the camera’s input.”
SEM-PRO. SEM with MIDI to CV Converter and integrated Patchpanel. This version combines the features of the MIDI to CV version with a 21-jack patchpanel and is personally autographed by Tom Oberheim.
- Select MIDI channel, controller number and bend range
- Select note assignment modes: latest, high note and low note priorities
- Select note re-trigger, filter track, LFO reset
- A second independent control bus allows velocity, controller data, or channel pressure to modulate either or both VCOs, the filter and the VCA
- Transpose function allows different keyboard controllers to utilize the complete MIDI note range
- Analog portamento
- Input preamp gain control – allows an external audio input to be processed thru the SEM
- High precision A-440 Hz tune signal
- Control voltages and gate are bought out to rear panel connectors so MIDI to CV function can be used with other CV/Gate gear.

About the synth:
The analog Matrix 1000 is essentially 1,000 Matrix 6 patches in a single-space compact rackmount MIDI module. It has the same synth architecture as the Matrix 6. Each of its 6 voices have two DCO’s (digitally controlled analog oscillator), a low pass filter, 2 VCA’s, 3 envelope gens, 2 LFO’s, and 2 ramp gens. The sounds are plentiful and good enough, however sounds can only be edited via MIDI, so you’ll need an external MIDI editor (such as MOTU’s Unisyn) or Access’ Matrix Programmer to edit parameters. You can also load sounds from the Matrix 6 via SysEx or software.
The Matrix 1000 provides an excellent source of pads, textures and ambient sounds. It has 195 “keyboard” sounds, 118 “strings”, 130 “woodwinds & perc”, 239 “synthesizer”, 119 “bass”, 74 “lead” and 125 “effects”. For the price, there is no better way to find genuine analog Oberheim Matrix sounds in a compact and very in-expensive rack module that is loaded with more sounds than you’ll ever need! The older versions of the Matrix 1000 have a black front-panel. The newer models in the ’90’s have a cream colored face-plate.
This video demonstrates the New England Analog Pyxis Expression System.
This adds expressive aftertouch to the keybed as well as a removable pressure sensitive pad that can both control the VCOs, VCF, and VCA in the synth. By pressing down on keys, or by pressing on the pad, players can bend one or both VCOs, swell the volume or open the filter of the synth. The Pyxis also has its own internal triangle/square wave LFO. The LFO is free running, and has the option of being modulated by pressure. The LFO amount can be dialed in to the VCOs, VCF, and VCA, and LFO will only be sent to these if pressure is being applied. The Pyxis LFO runs through 3 voltage controlled attenuators that are controlled by pressure. As the player presses harder on the sensors, more LFO will be sent to the modulation destination. This allows for an amazing array of interesting and organic sounds to be created.
The Pyxis is available as an internal installation or in a separate wood enclosure. It has the option of having aftertouch installed in the keybed of the synth (we must do this at our shop), or the pressure sensor pad. The sensor pad has a magnet underneath it to secure it to metal surfaces. It also sits firmly on any other flat surface. As shown in the video, a synth can have both the pressure pad and keybed aftertouch installed. The installation of the Pyxis varies from synth to synth. Monophonic and Duophonic synthesizers take the least time to install the system in, while polysynths usually take a few hours to do the installation in. The aftertouch installation also varies as well. Small keyboards like the ARP Odyssey, Pro One, Minimoog, Prodigy, Multimoog, etc. will take less time than Jupiters, OBX/OB8, Polysix, Monopoly, etc. We offer custom installations of aftertouch, breath control, and pressure controllers for all analog systems.
